Rear Panel
The
rear
panel
is
composed
of
the
following
components.
Fans
For
cooling,
the
rear
panel
of
the
NE10032O
has
six
bays
for
hot
‐
swap
fan
modules.
Six
fan
modules
are
required
for
redundancy.
When
six
fan
modules
are
used,
if
there
is
a
failure
of
one
of
the
fans,
the
switch
reports
the
condition,
the
other
fans
continue
to
run,
and
the
switch
continues
to
operate
normally.
You
can
replace
one
failed
hot
‐
swap
fan
module
while
the
switch
is
operating.
If
a
second
fan
fails,
the
switch
reports
the
condition
and
shuts
down
to
prevent
overheating.
Compatible
fan
options
are
listed
in
the
Fan
operation
and
internal
temperatures
are
monitored.
If
the
air
temperature
exceeds
a
desired
threshold,
the
environmental
monitor
displays
warnings.
Note:
If
a
fan
fails,
the
maximum
operating
temperature
drops
from
+40°C
(104°F)
to
+35°C
(95°F).
